Mainly the function is different.
Oil air compressor is the general use of electronic, printing, coating gas factory, oil-free air compressor is food, medicine, hospitals and so on.
Oil-free air compressor is cheaper, and oil-free air compressor is more expensive.
as long as the normal maintenance is quite durable
oil-free and durable.
1. materials are different:
1, oil air compressor: oil air compressor itself material containing oily substances, will pollute the terminal equipment.
2, oil-free air compressor: oil-free air compressor itself does not contain oily substances, to avoid the oil machine on the terminal equipment pollution.
2. gases are different:
1, oil air compressor: oil air compressor with oil lubrication, so the final discharge of the gas containing oil.
2. Oil-free air compressor: The oil-free air compressor is lubricated with resin material, so the final discharged gas does not contain oil.
gas circulation system
when the compressor is working, air is sucked in through the self-cleaning air filter, and the filter is automatically cleaned by PLC. The air enters the first-stage compression after being automatically adjusted by the inlet guide vane. The gas after the first-stage compression has a higher temperature and enters the intercooler for cooling (the water goes through the pipe, the air goes outside the pipe, and the water flow of the intercooler is required to be 110 m/h) and then enters the second-stage compression system.
In order to prevent the gas in the system from pouring into the compression cavity (avoid starting under pressure), a full-open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve into the exhaust muffler. Enter the primary aftercooler, the secondary aftercooler, and then enter the main exhaust pipe.
The quality standard of compressed air for food blown film is that the total oil content is below 0.01mg/m3. Compressed air for food film blowing has a standard oil content of 0.01mg/Nm3 and a gas production of 10 Nm3/min. The cumulative oil content in one hour is 6mg and 180g a month.
There are significant differences between scroll compressors and screw compressors in many aspects. These differences are mainly reflected in the working principle, structural characteristics, performance performance, applicable scenarios, and maintenance requirements. The following is a detailed explanation of the difference between the two: How the 1. works
The role of oil-free air compressors is mainly reflected in the following aspects: 1. provide high-quality compressed air. Oil-free air compressors compress atmospheric pressure into high-pressure air through special design and purification treatment devices, such as filters, and in the compression process Avoid the use of lubrication
When shutting down, it is usually recommended to close the air compressor first, and then close the cold dryer. The reason for this is that the air compressor produces a large amount of compressed air during operation, which is cooled and dried by the cold dryer. If the cold dryer is turned off first, then the air compressor
Answer: Frequency conversion direct screw air compressor has the following advantages: 1, energy saving effect is remarkable: through the intelligent control system, according to the actual demand automatically adjust the working speed, so as to effectively reduce energy consumption, save running
Air compressor faults and treatment methods The high temperature rise of the outlet temperature or exhaust temperature of the air compressor head is a common fault in the operation of the screw air compressor. The screw air compressor often runs at high temperature, which will seriously affect the displacement and operation of the machine.
The downstream industry's requirements for compressed air cleanliness and the trend of oil-free air compressors can be summarized as follows: 1. compressed air cleanliness requirements The downstream industry has strict requirements for compressed air cleanliness, which mainly depends on the industry
Whether the air compressor can always run depends on the design, manufacturing process, use environment, load situation and maintenance of the air compressor. In theory, if the air compressor is properly maintained and maintained, and the operating environment is good, it can be
Air compressor outlet dust content requirements are usually subject to the relevant standards and regulations. The following are some requirements for the export dust content of air compressors: National standards: In China, the working environment dust standards of air compressors are mainly affected by the national standard "Air Quality"
The special air compressor for the pharmaceutical industry plays a vital role in the pharmaceutical production, providing clean and stable air source for various medical equipment. The following are some of the characteristics and requirements of the special air compressor for the pharmaceutical industry: Features: high cleanliness: the pharmaceutical industry
